Hi,
I have function that I want to optimize. Am playing with the optim() function
in R
Two issues:
1) I can't seem to get it to work with a function that takes multiple inputs.
Dummy Example:
myFunc <- function(A,B,D,D){
# Do stuff
return E
}
> myFunc(1,2,3,4)
[1] 12
# works fine from command line
> optim( par=c(1,2,3,4), fn=myFunc)
Error in A+B : 'B' is missing
2) For SOME of the inputs, I want to fix the step size to integers. For
another input, I would also like to limit the range of possible values for
each input
The help file in R isn't very clear on either of the above issues.
Any suggestions?
Thanks!
